TRANSPARENT CONDUCTIVE FILM

摘要

PURPOSE:To obtain a phase difference, transparent electrical conductivity and excellent thermal stability by forming a transparent conductive film on one surface of an arom. polyester film having a retardation value within a specific range. CONSTITUTION:The transparent conductive film is formed on at least one surface of the arom. polyester film having the retardation value within the 100 to 8000nm range. The phase difference is too small and there is a need for using many sheets of the films in order to obtain a film for compensation if the retardation value is <100nm. Such is not practicable. Compensation performance does not change even if the above-mentioned value exceeds 800nm.
